  In the case of the present embodiment, the first exciter 224a is fixed to the rear surface of the outer edge portion of the see-through portion 307a, which is the position covered by the visor 308, using a fixing means described later. Specifically, as shown in FIG. 4, the fixing means 400 includes a protrusion 401 integrally formed on the see-through panel 307 (the see-through portion 307 a), and an elastic member 402 disposed so as to overlap behind the protrusion 401. It consists of a plate-like member 403 and two screws 404.

  The protrusion 401 has an annular shape surrounding the first exciter 224a, and is formed to protrude from the rear side of the fluoroscopic panel 307. The protruding end surface P1 is around the main body 224c, which is the main part of the first exciter 224a. It is set so as to be substantially flush with the back surface P2 of the extending substantially annular plate-like flange portion 224d. Further, the protruding portion 401 is formed with a pair of screwed portions 401 a for fixing the two screws 404 respectively.

  The elastic member 402 is made of a material having flexibility such as a cushion material or a spacer, and has a first opening 402a formed in a substantially circular shape corresponding to the main body 224c of the first exciter 224a. The first opening 402a is formed in a substantially annular shape having a first annular portion 402b surrounding the first opening 402a. In the first annular portion 402b, a pair of through-hole portions 402c are formed at positions corresponding to the screwed portions 401a of the protrusion 401.

  The plate-like member (restraining member) 403 includes a second opening 403a corresponding to the first opening 402a of the elastic member 402, and a second annular portion 403b surrounding the second opening 403a. It is made of a substantially annular plate-like synthetic resin material or the like, and its outer shape is set to be substantially the same as that of the elastic member 402. In the second annular portion 403b, a pair of holes 403c are formed at positions corresponding to the screw portions 401a of the protrusion 401 and the through holes 402c of the elastic member 402.

  When the first exciter 224a is assembled to the protrusion 401 integrally formed with the fluoroscopic panel 307 using the fixing means 400, the annular protrusion 401 is first directed upward on a fixing jig (not shown). The fluoroscopic panel 307 is set on the first exciter 224a, and the first exciter 224a is placed inside the annular protrusion 401 so that the vibrating body of the first exciter 224a and the fluoroscopic part 307a come into contact with each other. At this time, the back surface P2 of the flange portion 224d and the projecting end surface P1 of the projection portion 401 in the first exciter 224a are located on substantially the same plane with respect to the longitudinal direction (plate surface direction) of the see-through portion 307a. .

  Next, the first opening 402a of the elastic member 402 and the main body portion 224c of the first exciter 224a, and the through-hole portions 402c of the elastic member 402 and the screwed portions 401a of the protrusion 401 face (correspond). Thus, the elastic member 402 and the perspective panel 307 (projection 401) are aligned. Then, by moving the elastic member 402 as it is toward the see-through portion 307a side, the flange portion 224d and the projection portion 401 are located on the same plane with the main body portion 224c fitted into the first opening portion 402a. The elastic member 402 is placed on the surface.

  Next, the first opening 402a of the elastic member 402 and the second opening 403a of the plate-like member 403 are opposed to each through-hole portion 402c of the elastic member 402 and each hole 403c of the plate-like member 403 ( The elastic member 402 and the plate-like member 403 are aligned so that the plate-like member 403 is translated to the elastic member 402 side as it is, and the plate-like member 403 is placed on the elastic member 402.

  Finally, the screws 404 are passed through the holes 403c and the through holes 402c, and the through ends of the screws 404 are screwed into the screws 401a, whereby the perspective panel of the first exciter 224a. The assembly work to 307 is completed. The see-through panel 307 to which the first exciter 224a is attached is detached from the fixing jig and assembled to the cover member 309. Note that the number of screwed portions 401a, through-hole portions 402c, hole portions 403c, and screws 404 is not two as in the present embodiment, but may be three or more as required.

  Therefore, according to the present embodiment, by adopting the fixing means 400 including the protrusion 401, the elastic member 402, the plate-like member 403, and the screw 404, the surface of the vibrating body and the fluoroscopic panel 307 in the first exciter 224a. Since the first exciter 224a is fixed to the fluoroscopic panel 307 so as to contact the back surface, the vertical vibration of the vibrating body according to the electric signal, amplitude and phase is directly transmitted to the fluoroscopic panel 307 as flexural vibration. The

  Here, since the elastic member 402 is interposed between the see-through portion 307a (projection portion 401) of the see-through panel 307 and the plate-like member 403, the amount of bending vibration of the see-through panel 307 due to the vertical vibration of the vibrating body is reduced. It can prevent being restricted. That is, the fluoroscopic panel 307 and the plate-like member 403 are indirectly joined via the elastically deformable elastic member 402, so that the elastic member 402 is deformed (elasticized) in conjunction with the flexural vibration of the fluoroscopic panel 307. Therefore, the bending vibration amount of the fluoroscopic panel 307 is not restricted by the plate-like member 403. As a result, play (margin) can be given to the amount of flexural vibration of the fluoroscopic panel 307. Further, by adopting such fixing means 400, it is possible to mitigate external vibration applied to the first exciter 224a when the vehicle is traveling.

  In addition, although illustration is omitted, in the protrusion 401 of the fixing means 400 described above, a through portion including a through hole is formed instead of the screwed portion 401a, and the through portion is provided at the see-through portion 307a corresponding to the through portion. A hole to be communicated is formed, and a screw having a threaded portion longer than the screw 404 from the back of the plate-like member 403 in the fixing means 400 is inserted into the hole 403c, the through hole 402c, the through part, and the hole. The first exciter 224a may be fixed to the fluoroscopic panel 307 by penetrating and fixing the protruding end portion of the screw protruding to the surface side of the fluoroscopic portion 307a with a nut. Although not shown in FIG. 3, both ends of the voice coil in the first exciter 224a and the male connector 225b are electrically connected by a pair of electric cords (signal lines).

  The above-described units constitute a vehicle meter 101 (first pointer type display unit 103). The configuration of the second pointer-type display unit 104 is substantially the same as the configuration of the first pointer-type display unit 103 described above, and the second exciter 224b is the same as the first exciter 224a. It is fixed to the back surface of the outer edge portion of the see-through portion 307a, which is a position covered by 308, by a fixing means 400, and is not directly visible from the passenger side. Further, the display surface of the first display unit D1 is configured to be visible to the passenger through the turn-back member 306, the perspective panel 307, and the visor 308, similarly to the first pointer type display unit 103.

  Next, the operation of the vehicle information providing apparatus 100 will be described with reference to FIG. FIG. 5 shows an output example of the auditory information emitted from the auditory information providing means 220 for each hour.

  Specifically, the control unit 202 mixes the sound signal output from the portable audio device 213 through the audio terminal 214 at the time t1 (that is, the input signal from the portable audio device 213) of the auditory information providing unit 220. When it is detected that the sound signal is input to 222, control is performed so that the sound signal is output to the amplifier 223. At this time, the control means 202 reads the sound volume previously set by the passenger from the second storage means 204 and outputs the sound pressure A1 instruction to the mixing means 222 and the amplifier 223 with respect to the sound signal volume. Take control. Then, the sound signal simultaneously drives two exciters 224 (both the first and second exciters 224a and 224b) via the amplifier 223. Accordingly, since the vibrating bodies of the two exciters 224 vertically vibrate according to the amplitude and phase of the sound signal, the second auditory information is set to the sound pressure A1 from the fluoroscopic panel 307 by the vertical vibration. A sound signal (music) is emitted toward the passenger. This means that the occupant can hear the sound signal (music) set to the sound pressure A1 as if it was a sound emitted from the entire fluoroscopic panel 307.

  At time t2, the control unit 202 inputs the instruction signal output from the navigation device 215 via the navigation terminal 216 (that is, the input signal from the navigation device 215) to the mixing unit 222 of the auditory information providing unit 220. When this is detected, control is performed so that the instruction signal is mixed with the sound signal of the portable audio device 213 continuously input from time t1. Such mixing control is performed by the mixing means 222 of the auditory information providing means 220. At this time, the control unit 202 reads out the volume preset by the passenger from the second storage unit 204 with respect to the volume of the instruction signal, and outputs the sound pressure A3 instruction to the mixing unit 222 and the amplifier 223. Control. Then, the sound signal and the instruction signal that are mixed and output from the mixing unit 222 simultaneously drive the two exciters 224 via the amplifier 223. Accordingly, since the vibrating bodies of the two exciters 224 vertically vibrate according to the amplitude and phase of the sound signal and the instruction signal, the sound signal (second auditory information) is transmitted from the fluoroscopic panel 307 due to the vertical vibration. Music) and the instruction signal (for example, voice guidance information “Pawn, about 1 km at the entrance of a highway”) are mixed and emitted toward the passenger. This means that the occupant can hear the sound signal (music) and the instruction signal (voice guidance information) at the same time as if the sound was emitted from the entire fluoroscopic panel 307. .

  At this time, the sound signal (music) has a lower priority than the instruction signal (voice guidance information), and the sound signal (music) having a lower priority is the instruction signal having a higher priority. In order to make it easier to hear (voice guidance information), the mute instruction is given, and the sound pressure of the sound signal (music) is set to a sound pressure A2 smaller than the sound pressure A1. The sound pressure of the instruction signal (voice guidance information) is set to the sound pressure A3. However, in this case, the value obtained by adding (adding) the value of the sound pressure A2 and the value of the sound pressure A3 is substantially equal to the value of the sound pressure A1, and the sound pressure A3> the sound pressure A2. . Note that the priorities of the auditory information and the sound pressure set in the mute instruction are set in advance. As described above, when a plurality of auditory information is emitted simultaneously, the sound pressure of the auditory information having a low priority is made smaller than the sound pressure of the auditory information having a higher priority, regardless of the sound pressure set at the normal time. Information that is highly important for the passenger can be easily heard, contributing to safe driving and improving the functionality of the vehicle information providing apparatus.

  When the control means 202 receives that the instruction signal from the navigation device 215 is not input via the vehicle information terminal 212 at time t3, the control means 202 does not input the instruction signal (between time t1 and time t2). Similarly, the passenger can hear only the sound signal (music) as a sound emitted from the entire fluoroscopic panel 307. In this case, the sound pressure of the sound signal (music) is changed from the sound pressure A2 to the sound pressure A1 when the mute instruction is canceled by canceling the input of the instruction signal.

  When the control means 202 receives a predetermined alarm instruction signal (that is, an input signal from the vehicle information terminal 212) as the vehicle information via the vehicle information terminal 212 at time t4, the control means 202 is continuously input from time t3. Control is performed so that the alarm instruction signal is mixed with the sound signal of the portable audio device 213. Such mixing control is performed by the mixing means 222 of the auditory information providing means 220. At this time, the control means 202 reads out the volume preset by the passenger from the second storage means 204 with respect to the volume of the warning instruction signal, and outputs the sound pressure A4 instruction to the mixing means 222 and the amplifier 223. Control. Then, the sound signal and the alarm instruction signal that are mixed and output from the mixing unit 222 simultaneously drive the two exciters 224 via the amplifier 223. Accordingly, since the vibrating body of the two exciters 224 vertically vibrate according to the amplitude and phase of the sound signal and the alarm instruction signal, the sound signal as the second auditory information is transmitted from the fluoroscopic panel 307 by the vertical vibration. (Music) and the warning instruction signal (for example, a warning sound “The outside temperature is falling. There is a risk of road surface freezing”) as the first auditory information that alerts the passenger to the state of the vehicle. It is mixed and emitted toward the passenger side. This means that the passenger can hear the sound signal (music) and the warning instruction signal (warning sound) at the same time as if the sound is emitted from the entire fluoroscopic panel 307. .

  At this time, the sound signal (music) is set to have a lower priority than the alarm instruction signal (alarm sound), and the sound signal (music) having a lower priority is assigned to the alarm with a higher priority. The mute instruction is given to make it easier to hear the instruction signal (alarm sound), and the sound pressure of the sound signal (music) is set to a sound pressure A2 smaller than the sound pressure A1. The sound pressure of the instruction signal (the voice guidance information) is set to a sound pressure A4. However, in this case, the value obtained by adding (adding) the value of the sound pressure A2 and the value of the sound pressure A4 is substantially equal to the value of the sound pressure A1, and the sound pressure A4> the sound pressure A2. .

  When the control means 202 receives that the alarm instruction signal is not input via the vehicle information terminal 212 at time t5, the control means 202 is input before the alarm instruction signal is input (from time t1 to time t2 or from time t3 to time t4). In the same manner, the rider who is a rider can hear only the sound signal (music) as a sound emitted from the entire fluoroscopic panel 307. In this case, the sound pressure of the sound signal (music) is changed from the sound pressure A2 to the sound pressure A1 as the mute instruction is canceled by canceling the input of the warning instruction signal. The above is an example of the operation of the vehicle information providing apparatus 100.

Next, the volume setting function of the various sound sources of the vehicle information providing apparatus 100 according to the present embodiment will be described with reference to FIGS.
